There is nothing wrong with talking to God about oneself. Are you saying there is?
If you read what he wrote, he is most cerntianly not saying what you claim he is saying.
He is saying that asking for material possessions for yourself is wrong and self-centered.
Asking God for help, protection, healing is all fine, but asking God to bless you with material wealth is not.
Asking for something you desire---even materially---is not wrong! God instills desires in us, and He loves to provide for us the things we desire and ask for!John 14:13
You can ask for anything in my name, and I will do it, so that the Son can bring glory to the Father.John 14:14
Yes, ask me for anything in my name, and I will do it!John 15:16
You didn’t choose me. I chose you. I appointed you to go and produce lasting fruit, so that the Father will give you whatever you ask for, using my name.John 16:24b
...Ask, using my name, and you will receive, and you will have abundant joy.
